That seems like possibly a reasonable idea. I think whether it is property tax and maintence, or condo fees, or maintence and hook up fees, the important thing is to take a clear and realistic look at costs, including how/when they might rise. Something else to think about is if you will be able to socialize and make friends and not feel lonely if you are moving back and forth like that (some people can jump into communities quickly and some RV areas might have great ones, for others this might be a a big problem).
In our case, we bought a condo in a small buildingm with 21 units. The 21 owners own every bit of the building and land and we make decisions about who to hire for maintenence, etc. It's a brand new building and part of the initial rules are that we collect a ser amount oer sq meter that goes into a fund to cover major repairs later on. Moving/selling does not get that money back. So hopefully that protects against a large jump later on to cover an expense. For us, the amounts, are less than if we had a single family home and hired out maintenace work and yard work and had to cover major mainetence on our own every so often. Some condos we looked at, in buildings that had not set up good sized maintence funds from the get go, had large monthly fees to repay the costs of major maintenace that came up after 20 years. Others still had reasonable fees with good sized funds that were added to all the time. It was certainly not a consistent thing. Just as property taxes vary greatly from area to area and hook up fees probably vary, etc---you really have to look at specifics for you.
